Dataset: Active wing-pitching mechanism in hummingbird escape maneuvers

This dataset contains the wing kinematics and mass distribution of the two hummingbirds used in the study. The wing kinematics were reconstructed from digitized high-speed videos of flight experiment in Cheng et al (Journal of Experimental Biology 219 (22) (2016) 3518–3531.).  Wing mass distribution was scaled from experiment data of Ruby-throated hummingbirds.


## Description of the data and file structure

The dataset is organized as follows:

1) Under ./matlabScripts/

- Three angles of the wing (stroke, deviation, pitch)
- Angular velocities of wing (stroke, deviation, pitch)
- Wing aerodynamic torque (stroke, deviation, pitch)
- Wing inertial torque (stroke, deviation, pitch)
- Wing input torque (stroke, deviation, pitch)
- Wing aerodynamic power (stroke, deviation, pitch)
- Wing inertial power (stroke, deviation, pitch)
- Wing total power (stroke, deviation, pitch)
- Matlab script for processing these data

2) Under ./bird1/mesh3dFiles/

- Sequence of marker files at all time steps for bird 1; each contains the unstructured mesh of the wings/body, including connectivity, xyz coordinates and uvw velocities of each node. 


3) Under ./bird2/mesh3dFiles/

- Sequence of marker files at all time steps for bird 2; each contains the unstructured mesh of the wings/body, including connectivity, xyz coordinates and uvw velocities of each node.

4) Under ./wingMass_data/

- .xls file that contains wing mass distribution of the Ruby-throated as well as scaled Rivoli's hummingbird wings.
